Thank you for all of your comments! I have a really comfy office chair, but aside from the arms getting in the way, it does not raise up quite high enough. Amazon has a "Dot" rolling stool that looks comfy and won't break the bank ($50 for the purple version) ....may give that a whirl....literally, lol.
For some reason, the Amazon link won't copy....here is the stool at overstock, but it is more expensive than Amazon!
